Patent DE-4337070-A1 (DE)
Title: Solenoid operated valve for fuel injection system - determines duration of fuel injection phase in conjunction with reciprocating fuel feed pump having cylinder indexing sensor
Inventor: ENOMOTO SHIGEIKU
IPC: F02M59/36
Filed: 1993-10-29
Abstract: The solenoid operated valve for a fuel injection system has a valve-stem (27) and set (40, 41) such that its axial motion within the housing (31) enables a closure or alternatively a connection between the high pressure (36) and low-pressure ports of a reciprocating fuel feedpump (not shown) and cylinder indexing sensor. The closure is initiated by the attraction of a disc armature (26) against a compression spring (28) by the magnetic core (25a) when the coil (25b) is energised. De-energisation of the coil (25b) results in equalisation of the pressure due to the coupling of the ports (33, 36) and fuel injection ceases with return of the stem (27) and disc (26) subject to secondary regulation via the stop (29) and spring (30). ADVANTAGE - Has improved speed of response and requires smaller solenoid compared with alternative systems offering high pressure fuel injection.

Patent DE-4404063-A1 (DE)
Title: Method of controlling switching induction tube of IC engine
Inventor: STEINER MANFRED
IPC: F02M35/12
Filed: 1994-02-09
Abstract: The method involves reducing the length of the induction channel (3) when the power output of the engine exceeds a high setting. In the proposed method, the length of the induction channel is also reduced when the engine power output falls below a certain level. This is because running at idling or low load produces sonic vibrations which cause pressure differences of between 100 and 300 mbar, thus causing wear of the switching valves (8).

Title: Harvesting vehicle crop height measurement system
Inventor: SCHOENFELDER GERT DR ING
IPC: G06T7/593
Filed: 1994-04-02
Abstract: The system uses two synchronised video cameras (K1,K2) at a fixed vertical separation to capture images of the diffuse object edge (OB). The image information of the individual pixels occur in an appropriate sequence for calculation. A sequential algorithm is used to calculate the object height (Y3).

This allows both small and larger gaps to be sealed between the bonded substrates, as the liquid adhesive has a low to medium viscosity and the hardened glue shows a marked volume increase. Reaction adhesives based on (meth)acrylates and that contain azo-bis-isobutyronitrile as initiator and expanding agent are preferably used. The disclosed reaction adhesive is preferably used for gluing reactive coils.
Patent DE-4428159-A1 (DE)
Inventor: MARTIN JOHANNES
IPC: F23N5/08
Filed: 1994-08-09
Abstract: The temp. resulting from the combustion is used alone or in combination with other control parameters as the direct or indirect control parameter. The temp. dependent control parameters are detected by directly or indirectly measuring the exhaust gas temp. at a position screened from the radiation from the burner bed (18) and/or flame (24) radiation using an infrared measurement device (22). Indirect measurement of the exhaust gas temp. can be performed by measuring the temp. of a comparison body, e.g. a ceramic body, whose temp. is essentially only directly proportionally influenced by the exhaust gases, using an infrared measurement device.

Title: Fluid flow measurement method for open channel, chute or partially filled tube
Inventor: BIRKHOLZ MARIO
IPC: G01P5/24
Filed: 1994-12-07
Abstract: The method involves arranging a floating body (14) on the fluid channel (13) such that it is aligned in the flow direction. An ultrasonic signal is transmitted from one end of the float (14) to the base of the channel. The signal is received at the other end of the float (14). The average flow rate is calculated from the frequency shift or time difference between the transmitted signal and the received signal. The amount of fluid flow is then calculated from the average flow rate and the channel cross-section. Several ultrasonic signals at an angle to the longitudinal direction of the float (14) may be used to calculate the flow rate. At least one of these should be reflected from the side of the channel. The channel cross-section may be derived from the time between signal transmission and signal reception.
